特長
非水媒質における pH 測定 (例えばエタノール中の pH eなど) のためのダブルジャンクションシステムを備えた複合 pH 電極。
電極は、汚れに耐性のある固定グランドジョイントダイアフラムを装備しており、塩橋は自由に選択することができます (水性または非水性)。
塩橋として c(KCl) = 3 mol/L を使用する場合、保存液中での保存が推奨されます。その他の塩橋を使用する場合、使用するそれぞれの電解液中での保存が推奨されます。
出荷時、参照内部液 ("INNER FILLING") と塩橋 ("OUTER FILLING") 用の両方のチャンバには、c(KCl) = 3 mol/l が充填されています。

- Reliable measuring results over long periods of time can be guaranteed only if the pH glass membrane and the diaphragm receive preventive and regular care. Cleaning by etching with toxic chemicals or applying mechanical treatment to the diaphragm is not only complicated and expensive, it also accelerates the ageing of the pH glass electrode.The cleaning solution was developed for easy and gentle cleaning of pH glass electrodes. Regular use can considerably prolong their service life.This cleaning solution is also part of the pHit kit.
